Why Scientists Study Questions That May Never Be Answered

Scientists spend entire careers hunting answers to questions that might never be solved, and that's exactly what makes progress happen.

Scientific American's October issue celebrates the beauty of "impossible" questions in science. These are the mysteries researchers have wrestled with for decades or even centuries without definitive answers, like the nature of consciousness or the makeup of dark matter.

At first glance, dedicating your life to an unsolvable problem sounds frustrating. But history shows these impossible quests lead to discoveries that change everything.

Consider the Gila monster. Someone wondered how these lizards survive months without eating while keeping their blood sugar stable. There was no obvious payoff to answering this puzzle, yet that curiosity eventually led to GLP-1 drugs, the blockbuster medications now transforming weight loss and diabetes treatment.

Or take the alchemists who spent centuries trying to turn common metals into gold using a philosopher's stone. They never succeeded at their original goal, but along the way they established the entire field of chemistry and discovered distillation, a process now essential for water purification, pharmaceuticals, and even perfume making.

Mathematicians chased "squaring the circle" for over 2,000 years, trying to create a square with the same area as a circle using only a compass and straightedge. The proof that it was impossible required discovering transcendental numbers, which opened entirely new branches of mathematics.

Why This Inspires

Today's impossible questions are yielding similar unexpected gifts. Scientists studying consciousness to understand if it's even real have improved anesthesia safety. Their experiments with LSD and psilocybin revealed powerful treatments for depression and PTSD.

Physicists searching for dark matter haven't found it yet, but they've created incredibly sensitive detector technology and learned what dark matter isn't. Each failed attempt narrows the field and builds knowledge for the next generation.

Philosopher Tim Bayne notes that studying consciousness is particularly tricky because you need consciousness to study consciousness. Yet researchers keep pushing forward, driven by curiosity rather than guaranteed results.

Perhaps the real point isn't reaching a final answer. Humans are wired for curiosity and social connection, and impossible questions satisfy both. They force us to ask why, how, and what, constantly building on the discoveries and people who came before us.

As one physicist puts it, maybe searching for absolute truth was always too ambitious. The search itself, the meaning we create along the way, might be the actual destination.

Every breakthrough we enjoy today came from someone willing to chase a question without knowing where it would lead.
